Tuff Extra strong thread for high speed tapping

Totem fluteless taps are designed for cold forming internal threads for ductile and non ferrous metals like Aluminum ( Moulded, Die casting, Drawn, Rolled ), Brass ( Drawn, Rolled ), Copper ( Molded, Rolled ) Zinc etc., These taps do not have cutting cutting edges or the conventional flutes thus giving the taps greater rigidity.

Fluteless taps do not produce chips and can be used for high speed tapping thereby maintaining a high precision uniformity and good surface finish of the tapped thread.

Spirex used for blind hole trapping. High wear resistance for high speed trapping. For long production run on though materials.

Sprial Pointed For through hole tapping

These taps with a special geometry, are unique in their performance especially for high production runs and for through hole applications. A shorter thread length coupled with strong cutting edges and lower cutting torque enables the chips to be pushed forward and therefore better thread finish.

The taps can also be manufactured in M35 & M42 steels with various surface treatments like Blued, Nitrided, Titanium Nitride etc

Spirex for blind hole tapping:

Totem Spiral fluted taps are designed for blind hole tapping in a wide variety of materials, including Aluminum, Plastic and Cast Iron. Depending upon the application the Spiral flute angle is available in slow Spiral 15 degrees and fast spiral 35 degrees.

The strong cutting edges and short thread length enables reduce tapping torque resulting in higher performance. Spiral fluted taps can also supplied in M35 & M42 with various surface treatment like Steam tempered, Blued, Nitrided, Titanium Nitride etc.
